  "message": "[IA64] In syscall-entry, use st8 instead of stf8 to clear pt_regs.r8\n\nUsing stf8 seemed like a clever idea at the time, but stf8 forces\nthe cache-line to be invalidated in the L1D (if it happens to be\nthere already).  This patch eliminates a guaranteed L1D cache-miss\nand, by itself, is good for a 1-2 cycle improvement for heavy-weight\nsyscalls.\n\nSigned-off-by: David Mosberger-Tang \u003cdavidm@hpl.hp.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n",
